        <p>
            An <em>InternetGatewayDevice</em> connects a LAN to a WAN, and through UPnP supports the
            monitoring and configuration of LAN and WAN interfaces. Typically this functionality is used
            for NAT port mapping: A client application on the LAN wants to receive network connections
            from a WAN host, so it has to create a port forwarding and mapping on the LAN router.
